Diesel fuels contain highly toxic chemicals, one of which is benzene, a known carcinogen.  Even very small concentrations of benzene can contaminate water supplies. If benzene and other toxic chemicals seep into a community’s water, that’s a serious and possibly irreparable problem.  Congress recognized diesel’s extraordinary dangers back in 2005 when it passed the federal Energy Policy Act.  It exempted most oil and gas hydraulic drilling and fracturing from the Safe Drinking Water Act – but not fracking with diesel.

The reality is that the nation’s primary prairie and wetlands protection program – the USDA’s Conservation Reserve Program (CRP) – was not designed to meet the environmental challenges being created by record prices for farm commodities. Because the majority of the land in the program is taken out of agricultural production under 10- and 15-year rental agreements with the owners, cropland that had been “restored” with grasses and trees is increasingly being plowed under to grow crops again as soon as these agreements expire.
